Alright, let's solve this math problem step by step. First, we have the number 874. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 12. So, we're going to take the number 874 and add it to itself 12 times.
Step 1: 0 + 874 = 874
Step 2: 874 + 874 = 1748
Step 3: 1748 + 874 = 2622
Step 4: 2622 + 874 = 3496
Step 5: 3496 + 874 = 4370
Step 6: 4370 + 874 = 5244
Step 7: 5244 + 874 = 6118
Step 8: 6118 + 874 = 6992
Step 9: 6992 + 874 = 7866
Step 10: 7866 + 874 = 8740
Step 11: 8740 + 874 = 9614
Step 12: 9614 + 874 = 10488

So, 874*12 = 10488
